Shock absorber

Abstract

A shock absorber includes a plate and a lock portion. The plate is secured to a distal end side with respect to a nut of a piston rod by crimping the piston rod. The lock portion is disposed on a bottom portion side of a cylinder and locks the plate. The shock absorber is maintained in a contraction state by the plate being locked by the lock portion.

1 . A shock absorber comprising:
 a cylinder filled with operating fluid;   a piston slidably inserted into the cylinder;   a piston rod movably inserted into the cylinder, the piston rod penetrating the piston and being coupled to the piston by a nut;   a plate secured to a distal end side with respect to the nut of the piston rod by crimping the piston rod; and   a lock portion disposed on a bottom portion side of the cylinder, the lock portion being configured to lock the plate, wherein   the shock absorber is maintained in a contracted state by the plate being locked by the lock portion.   
     
     
         2 . The shock absorber according to  claim 1 , wherein
 the lock portion is formed on a locking member disposed on the bottom portion side of the cylinder.   
     
     
         3 . The shock absorber according to  claim 1 , wherein the lock portion is formed on the cylinder.
